"I'm sure you'll be happy to hear that every single one of our beers is a vegan product. We've never used any of the animal product-based processing aids, and I don't believe we ever will, as we'd be alienating a good chunk of our consumers and even some of our own employees."

"I'm sure you'll be happy to hear that every single one of our beers is a vegan product. We've never used any of the animal product-based processing aids, and I don't believe we ever will, as we'd be alienating a good chunk of our consumers and even some of our own employees. We only manufacture our beer here in good old Fort Collins, CO so you don't have to worry about any other processing systems."

Company email (May 2012):
"Thanks for your email. You will be happy to know that we don't use any kind of animal bi-products in our beers or during processing/filtration. Nor does any other company brew our beer, it's all brewed here at New Belgium."

Worker owned and powered by the wind!

Company email:
"Most of our beers do not contained refined sugar. The beer is made from the natural sugars we extract from malted barley as part of our process.
Abbey and Trippel have refined sugar added. We have a response back from our sugar supplier. All of our sugar is free of bone char."

Company email:

"None of the beers we are currently producing contain any animal-derived ingredients. In 2003 we used an animal derived processing aid called isinglass to clarify our first batch of Transatlantique kriek. This processing aid was removed from the beer by filtration prior to packaging so it might be considered vegan since it did not end up in the final product. Since that time we have discontinued the use of that processing aid. The brew number of that Transatlantique that was treated with isinglass is 14821 written on the bottom right hand corner of the label. This beer has passed its best buy date and should no longer be in the market. Aside from this instance all of our beers are vegan."
